Safety and Handling

Corrosive. Causes irreversible eye damage and skin burns. May be fatal if absorbed through skin. Prolonged or frequently repeated skin contact may cause allergic reactions in some individuals. Harmful if swallowed. For more information, see the Safety Data Sheet provided with this product.

Chemical Feeding and Control

Add 10 – 333 ppm of AWC D-115 into industrial ultra-filtration or reverse osmosis systems by either continuous feed or periodic injection. Compatibility of AWC D-115 with reverse osmosis membranes should be confirmed with membrane manufacturers. For the control of bacteria and fungi in carbon beds, add 10 -333 ppm of AWC D-115 by either continuous or batch feed. For periodic membrane cleaning, add 400 -1000 ppm of AWC D-115 into cleaning solution and circulate. Badly fouled systems should be cleaned before treatment is begun.
